Two-bubble interaction has wide applications, such as cavitation, seabed exploration and underwater explosions, in which bubble collapse and jetting are the most focused issues. Based on the incompressible potential flow theory coupled with the boundary integral method, we investigate the dynamics of two differently sized bubbles. After jets penetrate the two bubbles, vortex rings model is introduced...
On the basis of boundary element method, this paper constructs a numerical model of underwater explosion bubble, and then develops singularities approximation method of bubble induced flow field from the view point of potential flow theory. A point source is adopted to simulate bubble pulsation, and meanwhile a point dipole is applied to simulate asymmetry caused by both the migration and deformation...
